I was very skeptical with passwords. My mac keychain was too cumbersome and complicated so I saved them all to a GnuPG encrypted file that I version controlled in Git. Way over complicated and I still had to remember them so I could use them on other computers (public and iPhone). LastPass really fixed all this. It a tiny bit hackish being web based. But hey found a way to integrate it into the browsing experience seamlessly. After a day of use I love it. I finally can use good passwords because LastPass memorizes it for me. Security at last. Awesome product highly recommend it.
